Setting Up Test Environment

To execute HAL L3 Python test cases, need a Python environment. Follow these steps mentioned in HPK Public Documentation

Update Configuration Files

Rack Configuration File

It identifies the rack configuration and platform used. We need to update our target device specif information in the rackconfig.yaml. In this file, update the configuration to define the console sessions for the device under test (DUT) Example Rack configuration File: ut/host/tests/configs/example_rack_config.yml
- For more details refer RAFT and example_rack_config.yml

In this file, update the configuration to define the console sessions for the DUT and the outbound settings:

Console Session	Description
default	Downloads the streams required for test cases.
ssh_player	Plays the stream required for test case.
ssh_hal_test	Executes the HAL binary for the test case.

rackConfig:
 - dut:
     ip: "XXX.XXX.XXX.XXX"  # IP Address of the device
     description: "stb device under test"
     platform: "stb"
     consoles:
       - default:
           type: "ssh"
           port: 10022
           username: "root"
           ip: "XXX.XXX.XXX" # IP address of the device
           password: ' '
       - ssh_player:
           type: "ssh"
           port: 10022
           username: "root"
           ip: "XXX.XXX.XXX" # IP address of the device
           password: ' '
       - ssh_hal_test:
           type: "ssh"
           port: 10022
           username: "root"
           ip: "XXX.XXX.XXX" # IP address of the device
           password: ' '
     outbound:
       download_url: "tftp://tftp-server.com/rack1/slot1/"    # Download location for the CPE device
       upload_url: "sftp://server-address/home/workspace/tftp/rack1/slot1/" # Upload location
       upload_url_base_dir: "sftp://server-address/home/workspace/tftp/rack1/slot1"
       httpProxy:   # Local proxy if required
       workspaceDirectory: './logs/workspace'   # Local working directory

Device Configuration File

Example Device configuration File: ut/host/tests/configs/deviceConfig.yml

For more details refer RAFT and example_device_config.yml

Update the target directory where HAL binaries will be copied into the device. Also, map the profile to the source/sink settings YAML file path.

Ensure the platform should match with the DUT platform in Rack Configuration

deviceConfig:
  cpe1:
    platform: "stb"    # Must match the platform in example_rack_config.yml
    model: "uk"
    target_directory: "/tmp"  # Path where HAL binaries are copied in device
    test:
      profile: "../../../../profiles/source/Source_4K_VideoPort.yaml"
      player:
        tool: "gstreamer"
        prerequisites:
          - export xxxx    # Pre-commands required to play the stream

Test Setup Configuration File

Update the artifact paths from which the binaries should be copied to the device.

Set the execution paths and provide the stream paths for each test case.

If a test case requires multiple streams or needs to be validated using several streams, ensure that all necessary streams are added sequentially for that specific test case.

Example configuration file: dsVideoPort_L3_testSetup.yml.

Test Suite Configuration

Update the execute command according to the device path where HAL binaries are copied and Update the test suite for each level test case

Example configuration file: dsVideoPort_test_suite.yml.

Run Test Cases

Once the environment is set up, you can execute the test cases with the following command

python <TestCaseName.py> --config </PATH>/ut/host/tests/configs/example_rack_config.yml --deviceConfig </PATH>/ut/host/tests/configs/deviceConfig.yml

Test Case Procedure

dsVideoPort_test1_VerifyVideoContent_Format_Callback.py

Overview:

This test plays pre-defined streams in various video content formats (HDR, HLG, Dolby Vision, etc.) and checks if the appropriate callbacks are triggered when the video format changes.

Platform Supported:

Sink

User Input Required:

No

Acceptance Criteria:

Play the pre-defined streams with different video content formats (HDR, HLG, Dolby Vision, etc.) and check that the callbacks are triggered when the video content format changes.

Expected Results:

The test will download and play multiple streams, each corresponding to a specific video format, and verify that the expected callbacks are triggered. After playback, the streams will be removed, and the test will pass if all expected callbacks are received.

Test Steps:

Run the Python file dsVideoPort_test1_VerifyVideoContent_Format_Callback.py with the required configuration:

dsVideoPort_test1_VerifyVideoContent_Format_Callback.py --config /host/tests/configs/example_rack_config.yml --deviceConfig /host/tests/configs/deviceConfig.yml

The test will download the required assets and begin execution, playing streams in various formats.
For each video format, the test will verify that the appropriate callbacks are triggered:
- NONE Video Format Callback
- HDR10 Video Format Callback
- HLG Video Format Callback
- Dolby Vision Video Format Callback
- HDR10PLUS Video Format Callback
- SDR Video Format Callback
The test will pass if all the required callbacks are detected; otherwise, it will fail.

dsVideoPort_test2_EnableDisableAndVerifyPortStatus.py

Platform Supported:

Source, Sink

User Input Required:

Yes:User input is required to verify whether the video is playing or not with prompt question Is Video Display on the port? (Y/N) (This will be automated later).

Acceptance Criteria:

Verify the Display by enabling and disable each supported video port.

Expected Results:

The video is visible when the port is enabled and goes blank when the port is disabled. User responses (Y/N) will determine if the test passes.

Test Steps:

Run the Python file dsVideoPort_test2_EnableDisableAndVerifyPortStatus.py with the appropriate configuration:

dsVideoPort_test2_EnableDisableAndVerifyPortStatus.py --config /host/tests/configs/example_rack_config.yml --deviceConfig /host/tests/configs/deviceConfig.yml

dsVideoPort_test3_VerifyHDCP_Version.py

Overview:

This test is designed to verify the correct HDCP version used during video playback. The test will specifically enable HDCP 2.2 encryption and ask the user to confirm the version displayed using an AV analyzer connected to the video output. The user must verify if the correct HDCP version is being used.

Platform Supported:

Source, Sink

User Input Required:

Yes: The user is required to verify the HDCP version on an external AV analyzer connected to the device. (This will be automated later).

The test will pass if the user confirms that the correct HDCP version is being used.

dsVideoPort_test4_VerifyResolution.py

Overview:

This test verifies the resolution settings supported by the source device. It sets different resolutions and checks additional parameters, including aspect ratio, SS mode, frame rate, and scan mode.

Source

User Input Required:

Yes: The user must verify the video resolution and other attributes (aspect ratio, SS mode, frame rate, scan mode) using a connected AV analyzer. (This will be automated later).

Acceptance Criteria:

The user verifies that the correct resolution, aspect ratio, SS mode, frame rate, and scan mode are displayed on the AV analyzer for each tested video resolution.

Expected Results:

The test sets various resolutions on the video output and prompts the user to confirm the correctness of the settings via an AV analyzer. If all settings match, the test will pass

Test Steps:

Run the Python file dsVideoPort_test4_VerifyResolution.py with the appropriate configuration:

dsVideoPort_test4_VerifyResolution.py --config /host/tests/configs/example_rack_config.yml --deviceConfig /host/tests/configs/deviceConfig.yml

The test will download the required artifacts and streams, then copy them to the target directory.
For each supported resolution, the test will set the following parameters and prompt the user for confirmation using an AV analyzer:
- Resolution (e.g., 720x480, 1920x1080)
- Aspect Ratio (e.g., 4:3, 16:9)
- SS Mode (e.g., 2D, 3D)
- Frame Rate (e.g., 29.97, 60 Hz)
